    From the headline I assume that you want to solve for x.

    1. Multiply both sides of the equation by x to get rid of the denominator:

    xy = 2x + 1 + x ==> 2x + x - xy + 1 = 0 ==> 2x + (1-y)x +1 = 0

    2. This is a quadratic equation in x which you can solve by the formula:

    x = -(1-y)/(4) √((1-y) - 8)/16)

    Hello!

    Is that all the information you have because you cant solve the equation as you have two variables x and y. You can transpose to make x the subject to get x = y - 1 / 2 - y.

    So you cant solve unless you gat a value of y to input.
